A Research Data Zone is a collection of interconnected and networked facilities, tools and services, allowing researchers to conduct scientific work on and with large (and small) volumes of data. One of the most basic parts of an RDZ is a network that facilitates high-bandwidth traffic and research data to both campus and various national and international partners and collaborators, without being encumbered by bottlenecks or impediments such as undersized or ill performing firewalls or badly engineered network links.
